To all 'whom it may concern:

Be it known that I, HEINRICH D iiEwELL, subject of the German Emperor,residing at Charlottenburg, Germany7 have invented.

i 970,694, dated September th, 1910` I have described a device by meansof which, when Setting typo by means of register bands any errors can'be made inoperative. when making the band, definite groupsot holes inthe band, which represent lines, words or individual characters, beingmade inoperative. In this arrangement the type space indicating devicemust be correctly setin eat-li rase, which operation is effected by thepaper carriage. ofthe typewriter connected with the bandperforatingdevice being moved backward. As the feed of the papercarriage corresponds exactly .with the width 'of the printed letter tobe set, every optional group of characters can be made inoperative` theposition of the paper carriage or the written line indicating' thecorrect length to be adjusted. The composer, however, who is making theband must pay considerable attention to the adjustment of the papercarriage j, in the event of its not returning into the position forbeginning a line.

A rough ad- .justment of the carriage maylead to'incorrect length ofline. Aceording'to my present invention the paper carriage is adjustedcorrectly automatically both when doing away 'with a defective line. andalso when removing incorrectly written words which occurs mostfrequently. In this' lnaniiernnexact adjustments are avoided.

1 According to pending application the perforated word separatingsymbol,v which causes the spaceA member to be set, forms the one limitot a groupof holes ivhieli'represents an incorreetly written ivord whichis to be made inoperative. Now according to my present. invention, whenperforating this symbol a stop or'iilautn'ient is adjusted which limitsthe backward movement of the lpaper. carriage the' eventl of. the wordlast. written being removed. The stop is adjustcdat each pressureon theWord separating key before the '.ie above mentioned cti-' paper carriageis fed forward by depressing the Wordseparating key. For this purposethe stop iscaused to .follow the movement of the pa )er carriage or of'an intermediate member connected therewith the amount of the totalWidth of the word last written u`n` til it contacts withasecond stoparranged on the paper carriage or on an intermediate member. The firststopv is fixed again until the next time the Word se arating key isused. At the end of the line the stop together with the paper carriageis'rcturned into the position for beginning a line.

The keys by means of which incorrectly made groups of holes are madeinoperative are designated hereinafter as Wordcancel ing key andline-canceling key. In addition the line-separating key and the wordseparating key come into consideration. lAll the other keys aredesignated briely as type' 4inveiition is not limitedj," however, tothis form. On the contrary," type snace indicators of every kind can beprovi ed 'with the means according to this invention and be therebyarranged forcorrecting parts of matter. Also, the mechanical devices canbe varied in manifold ways without departing from the spirit and sco eof my invention.

` l' te erring to the drawings, in the body or frame 1 of thetypewriter'the type levers90 5 and 91 are mounted in suitable manner andconnected by draw rods 92 with. levers 93. These are arranged on shafts94, which, on the one hand, carry at one end levers 95 and are soconnected by these with thekp'ys 96 that., when a key -is depressed, oneof th shafts 91is rotated, and the levers 93 act by means of the drawrods 92 on the type levers 90 so that' the type 97 corresponding -to thekey which has been depressed strikes against the platen roll, whereby animpression of the type is obtained by means of the ribbon 98 locatedbetween the type and the -platen roll. On the other hand, the shafts 94are carried at their other end in the frame of the perforating apparatusand are journa led therein at 100 and 101. They traverse a number ofplates 102g, 102b and 102, 102, as well as eleven plates 103. Theplates-102@l to 102d influence the feeding mechanism of the papercarriage, while the plates 103 effeetthe selection of the punches. Thenany key is depressed the corresponding shaft 911 is'rotated andplates103 or 102` to 102r1 are displaced. This displacement is broughtabout as t'ollows -In each of the plates 102l to 102dj and 103 isprovided for each shaft a recess 101 and Within this vrecess two teethor shoulders 105 and 106 Fig.I 5. riphery of each shaft 91 are ribs orprojec tions 107 and 4108 arranged diam frically opposite one anothe Butthe projections 107 and 108are so t isplaced longitudinally of the shaftrelatively to one. another that a gap on .the 'one side alwayscorresponds to a ribou the other side. The shafts 94C are divided into'two groups as seen in vsection in Fig'.

Each of the plates 103 has an extensionl 110 running out into a hook111. The latter engages in a hook 112 of an angledever ing to a keybeingstruck, the angle lever 113 rocks under the action ofthe sp1-in 1116 about the roundhead 117 of the punc 114 and the extension orshoulder 115 arrives in front of the 4strikin bar 118. Whenever a key.is struck two of t e plates 103 are moved, and leach of these platescorresponds toa special punch which is rendered operative in thedescribed manner bygthe displacement of the plates owing to the extensin115 corresponding to the punch in question arriving in front ofthestriking bar 118, and when the key moves further a special coupling', is

released whereby the mainf'shaft 7 8 of the:

perforating'apparatus is operated. 4At'this shaft is a ca'm 121 which,when the main shaft' rotates, impels the ybar 118 forward. lby means ofthe roller 122. This forward movement takes place during the third.quarter cfa revolution of the main shaft and'has' terminated at thevcommencement of the fourth' quarter. At this moment the v'rith-- drawalof the bar 118 begins bv means ofthe'v` angle lever 123 and the roller.124, on which thebam 121 gacts, when'the forward move;4 ment ofthe'striki'ng bar isterminated..I

In order thatthe point ofthe lever 113 can slide unlnpededly over the bar 120 whenthe punches are driven forward, at the moment when the.. punchesl aredriven forward the bar 120 is moved downwardly -by the projection 121 ofthe cam 12,1" so thatv it does not contact wit .the point of the levers113` `The plates -102a to 102d have extensions 130 and 131 which coactlwith the vertical I'arms 132 'and '133. of angle levers.

The devices for securing the paperon the platen roll, for raising theplaten roll and for rotating thesaine are not. shown because they maybe constructed in optional manner.and are sutlieiently4 well-known. operation is not relevant` to thepresent in' Their mode of vention. On the fran'1e2 of the papercarriageis secured a rack 10 with which a pinion 11 meshes. The latteris on an axle 12 which, on the one hand, is journaled at 12* in the'.typewriter and, on the other hand, at 1`2fl and '1,2c in the frame ofthe perforating apparatus-land carries the vgear wheel 13. (Fig. 2'.) In contradistinction to the ordinary arrangement a' spring'tends to:bring the paper carriageconstantly into the .position which thecarriage occupies when b e- 'ginning a line.'l When Writing, the pa percarriage is fed by feeding mechanism which worksA against thezspringJand is driven by the mechanical force serving for perforating 'the paperband. Y This arrangement makes it possible for the pa er carriagetojnove backward automatical have b een'struck,` namely after thedepression'v ofthe end-of-line key,:the line-canceling key or theword-canceling key. The

vgear Wheel 13 'meshes with a'gear Wheel 1 4 which. runs loosel on theaxle 15. This `axle carries secure on it another gear Wheel 2 2-whichmeShesZWith the wheel l-21 secured on `the faxle 20 of theieedingmechanism'.

This Afeeding mechanism' comprises 'four wheels 1 6, 17, 18 and 19 whichcan be rotated independently one of another (Fig. 3).

," after ldefinite keys These Wheels are?v moved by pawls which are lcoupled in. siiitablc manner, means 'of universal barsrnoved 'by thekeys, with the source offpowefggoperating the punching device.` Thelnotonimparted to the rWheels is added inl known manner byditl'erentialgearing-"anfd imparted to the axle 20, by which the axle '15 is driven'with tlie intermediary of the gear wheels 21 and 22..` This axleimparts its rotatory otiontojthe wheel 14 by means of a detacha leclutch comprisingitwo crown Wheels 37 a'nd 38. The crown wheel'vcomprises a-,l'o-w'erful disk 25 (Figs. S`

and- 9) p rovid'd atits edge with axial4 grooves 26 In these groovesrods 27 move axially, sald rods being shaped like a' ratchet. tooth atone end and -at the other carry a round extension 4254 around 'which aspring 2f) is arranged.- Each rod 27 has a flange-like. enlargement 30which limits''i'ts" displacement. The disk 25.is firmly connected with'the axle 15. i

Betweenl the disk 25L and the flanges 30 'isa disk ltagainst whichtheflanges'abut and which serves forholding 'back 'all'v the rods 27against the action et the springs 29. l To l'this end,- the disk 31 'isintegral with a 'bushing 32 havingfaange 33.A .By means. of j a lever34,whfo'se 'forked end claspsthe bushing2,ffthelatter-can be movedaxially. A casing is pushed over the rods 27., and the disk 25 preventsthe rods 27 'falling out of the"grooves 26 and supports the springs .29by means of its end 36. The extensions '28 are guided in holes in theend 36. The disk 25 with the projcJting, ends of the rods 27 formed asteeth forms a.

crown wheel with movable teeth which can be pressed back individuallyand independently one of another. This crown wheel will be hereinafterbriefly designated crown wheel 37. Opposite the teeth of the rods 27 isa crown wheel 38 provided with oppositelydirccted, fixed teeth andsecured to or integral with the gear wheel. 14.

The latter is free to rotate on, the axle 15.

'site'the crown wheel-42 is a crownwheel 45 Vprovided with `-movableteeth 44; These teeth are moved toward the crown wheel 42 -3'0 byspringsand tend to engage in the ratchetl teeth of the latterwheel.- Onthe wheel 45 is -also'an axially displaceable bushing-46 having lianges47 and 48. By means of these fianges andwit-h the intermediary of theley vers 49 and 50, which engage like forks around the bushing 46, theteeth 44 ofthe l,wheel 4 5 can be ,displaced and removed from the crownAwljxeel`42. The crown wheel 45 is free to rotate, but is axiallynon-displace# h able on the axle 15 and is 'prevented fromro- -tating bya noseor projection.51"located between a lfixed stop 52 and an elasticstop 5,3.

. (Figs. V2 and 7.) The stop 53 is aile'ver revo- Vluble around a pivot54 land under the action of a'pow'erful spring 55. By `means of thelever 53 this spring presses the nose 51' againstt-he v stop 52 andthereby'elas tically secures .the crown wheel 45 in its position. Thisarrangement forms a'- buffer i elastic so that great Awear and'tear ofthe device,.by which the limit stop for' the backward motion of; thepaper carriage is made gearwheels and other'parts is avoided. The

' crown wheels 37, 38,42 and 45 form two .dc-

tachable clutches, of,V which one comprises the crown wheels 37' and 3.8andthe otherthe' crown wheels 42and'45. The former clutch isdisconnected whenever the paper carriage returns, and the latter' whenthepaper 'carriage'jreturns into `the position atfthe beginningfof theline, and, in addition, 4when perforating the iWord separating symbol.

4As the paper carriage is fed yvarious distances "wllich are graduatedaccording to Ysmall units, provision must be made in the 4clutches thatthe papercarriage is held fast,

independently'of the position ofthe axle 15,

exactly at thatpoint up to which it is to movebackward and 4coup ed withthe ratchet mechanism. To this end, eithe' the c rown wheels of theclutches must have very fine teeth or, as in the present instance,special arrangements must be made which. assure lthe paper carriage beinfinally adjusted.

VIn thelv illustrative embodiment this is effected by means of themovable te'eth of the crown wheels 137 and 45 as follows: TheA crownwheels 38 and 42 each have 56 teeth.

Opposite each of these teeth are the movable ratchet teeth of the crownwheels 37 and 45. The number of teeth of two opposite-crown Wheels thus.form relative prime numbers. Consequently, of the'l teeth of the crownwheel 37 only one tooth can enter eachftime entirely into an oppositetooth gap of the wheel 38, While the remainin teeth do not or onlypartially en'gage in t e teeth gaps of the wheel 38. The number ofthevarious reciprocal positions which the two wheels 43*( and 38 canoccuply relativelv to (e ane en-` other, each .of whic *is assured bygagement of one movable tooth in a tooth gap of the opposite crownwheel, is equal to the product of the two numbers of teeth,

'thus in the case in question 840, 'so that :the

dilerencet in the position of the pa er 'carriage amounts toonly 1/840thpart o a rev0' lution. The same tine adjustment is obtained in thecase-'of the'crown wheels 42 and 4.5, mamans @which the stop 401s adjusted. 'Itfisito be noted'here that the post,

tion of the,stbp 40 must be 'assured in two directions, ,ti-n1 theone'h'and against the action of the spring 43 tending to' move the. stopin the direction of the normal rotationA of the wheel 14, andl on the-Iother-hand :against a rearwardmotion by the paper car- `ri age, Aorbythe stop 39, when -thejpaper carriageV is to be placedbackwardj-*tothis stop. Now'the ratchet teeth of thel` wheels 142 and40, are soarr'an ed 'that the motion of .the stop 4 0, which mlght beA broughtrabout y bfy the rearwardly-moving paperfcarriage,

must vtake place opposite to the :direction-of 'the ratchet teeth,sothat a toogreat rear-f -ward "movement `is rendered impossible. Thereverse motion, however, is not" ossible without disconnecting theclutch etween fthe wheels 42ar'1d 45, because inathis event .the-sprin43`Would have toinove backa number o teeth ofthe wheel 45.` "This-can bereadilyl prevented by making the springs which keep these teeth inengagement with the wheel 42 suliiciently 'powerful .toi-'ottersufficient resistance to the action of fthe spring 43. Theclutchesjormed* byjthe crown wheels' are disconnected-in each case,as'requu-ed, by means of the levers 34, 49 and 50.

In thisevent the shaft 70 is coupledwith-the source ofpower operating the perforatingr4 apparatus, whereuponit rotates once and then automatically stops. The coupling devices arenot more particularly described because they may be made in any optionalmanner well-known in itself. In the normalposition of shaft 7 0 therollers 53 and 72 are in recesses in the cams 5,9 and 71. If the shaft70 is moved by striking the end-of-li-ne key or the line-canceling key,the rollersi 58 and 72 are forced out of the Irecesses in the cams 59and 71 and cause the.

whenl the pawl .|151 falls into a gap in the crown wheel thisdiskiscompelled to participate in the rotation of the wheel. With thedisk is firmly 'connected the auxiliary 'shaft so that this also mustparticipatein the rotation of the wheel. In its position of rest thepawl is prevented by a, lever 1551frombeing connected with the crownWheel, but

'when this lever is pulled away thepawl is connected with the crownwheel and .the auxiliary shaft rotates with the grooved pulley 148. :Butbefore one rotation is 1invishedl, the lever 155 returnsinto its. normalposition and a'slanting face 156 on the lever receives tliepawl ll'andlifts it out. of the teeth of the crown wheel.- The clutch whichtemporarily connects the grooved pulleysv .145, 146 witlrthe main shaft78 is arranged in exactly similar manner.
